Title:
REINFORCED RECYCLED BLOCK/AGGREGATE CONCRETE PRECAST COLUMN AND CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/052387
Kind Code:
A1
Abstract:
A reinforced recycled block/aggregate concrete precast column and a construction method therefor. The reinforced recycled block/aggregate concrete precast column comprises several first one-bar hoops (1), vertical reinforcement bars (2), several second one-bar hoops (3), a flexible hinge area (4), and recycled block/aggregate concrete; the first one-bar hoops (1) and second one-bar hoops (3) are each provided with an anchor end; the first one-bar hoops (1) and second one-bar hoops (3) are disposed in the flexible hinge area (4), and only the second one-bar hoops (3) are disposed outside the flexible hinge area (4); the outer edge of each first one-bar hoop (1) is flush with the outer surface of the reinforced recycled block/aggregate concrete precast column; and the interior of the reinforced recycled block/aggregate concrete precast column is filled with the recycled block/aggregate concrete, thereby greatly increasing the recycling rate of engineering waste, reducing shedding of a concrete protective layer in the flexible hinge area of the column, and improving the restraint capacity of the hoops and construction efficiency.
